Specification forming part of Letters Patent No. 118,334, dated August22, 1871.

To all whom 'it may concern:

Beit known that we, JOHN BRADY and CEARLEs LAFAYETTE WALL, ofPhiladelphia, coimty of Philadelphia, State of Pennsylvania, have invented an Improved Ash-Sifter, of which the following is a specification:

Our invention consists of apparatus, too fully explained hereafter toneed preliminary description, for effectually separating from wasteashes the cinders which are available for consumption as fuel.

Figure l is a vertical section of our improved ash-sifter; Fig. 2, atransverse vertical section on the line l 2, Fig. l; Fig. 3, aperspective view of the upper portion ofthe ash-sifter; Fig. 4, a per-Yspective view, partly in section, of the body of the same; Fig. 5, aperspective view of the base; and Fig. 6, an enlarged view of va portionof one of the sieves or screens.

The body of the sifter consists of a rectangular box, A, within whichare arranged two screens or sieves, B and X, one inclinedin a contrarydirection to the other. The upper end ofthe screen B extends from thefront edge of the opening a at the top of the box to the lower edge ofan opening in an inclined chute, E, the bottom of the latter, consistingof the above-mention ed screen X, which, together with the sides c ofthe chute, extend from the rear b to the front b of the box A, where thechute communicates with an opening, h, inthe above-1nentioned front b ofthe box. Two inclined planes, i i, best observed in Fig. 4,

are so arranged as to meet at the top in a sharpedge, these planesextending to the front b of the box.

It will be observed, in referring to Fig. 2, that the chute E isnarrower than the interior of the box is wide, so that there may bespaces y on each side of the chute for a purpose described hereafter.

At the top of the box A is a detachable hopper, D, for directing theunsifted ashes to the opening' a, and to the top of this hopper may beso secured one edge of a flap of leather or fabric that it can be thrownback, as shown in Fig. 3, or turned over the top of the hopper, as shownin Fig. l, Where it will prevent the dispersing of the ashes. The lowerend of the box A is so iitted to the receptacle H for the waste ashesthat it can be readily detached therefrom.

Combined ashes and cinders raked from aiireplace are thrown into thehopper, whence they fall onto the inclined sieve or screen B and passdown the latter, a great portion of the fine ashes falling through themeshes of the screen onto the top of the chute E, or onto the inclinedplanes or delectors i i, which direct the ashes to the spaces y y,through which they fall into the receptacle The partially-sifted cinderspass from the screen B onto the second inclined screen X, the siftedcinders being iinally discharged through the chute E and opening h inthe front ofthe box,

ready for use as fuel, while the remaining line ashes pass through themeshes of the said sieve X and into the receptacle H. In passing downthe iirst screen the ashes are not thoroughly sifted from the cinders,owing to both descending together in a comparatively undisturbed volume;but the moment this volume passes through the opening f of the chute andturns in the direction of the next screen X it is entirely broken up,and so thoroughly disturbed that the remaining ashes are at liberty topass through the second screen, while the sifted cinders are dischargedin front of the box.

If desired, the above-described sifter may extend from the floor to therafters of a cellar, and the opening a may be in the kitchen-floor andthe hopper attached to the same, so that a cook may from time to timethrow the ashes into the hopper and collect the sifted cinders wheneverit is convenient to do so.

It will be seen, on referring to Fig. 6, that the meshes of the screenare longer than they are wide, the narrow meshes being arrangedtransversely in the box.

Three or even more than three screens may be used if the height of thebox will permit, but we have found that two will suffice if placed at aproper inclination.

Instead of two deliectors, it', one deiiector only may be used, andarranged to extend from one edge of the chute to the side of the box, asshown by the dotted line m, Fig. 2, the waste ashes from the upperscreen being in this oase directed to a single space7 y, between thechute and adjacent side of the box.

I claim- An ash-sifter, consisting of the box A, screen B X, chute Econtracted to form the side spaces y y, and detachable hopper D having afcxible flap, the whole being constructed and arranged as described.

In testimony whereof we have signed ournames to this specification inthe presence of two subscribing witnesses.
